BRICK OR TILE CUT-OFF MACHINE.

SPECIFICATION forming part of Letter Application filed September 27, 1888.

To aZZ whom it may concern.-

Be it known that 1, WILLIAM W. WALLACE, of IVilloughby, in the county of Lake and State of Ohio,have invented certain new and useful Improvements in Out-01f Mechanism for Tile or Brick Tables; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in cut-off mechanism for tile or brick tables; and it consists in certain features of construction and in combination of parts, hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a front end elevation. Fig. 2 is a side elevation.

A A represent metal side frames, the same being secured to metal cross frames 13 B. These cross-frames are open. on what I will call the back side, as shown in Fig. 1, so that by removing some of thelighter members of the machine and relaxing the endless apron F the latter intact can be removed from the table. The legs of the table consist of upright screw-threaded rods 13 with feet I) attached. These screw rods or legs are held in sockets B of the cross-frames, and the threads of the rods engage nuts I), the latter being in the form of hand wheels, by manipulating which hand-wheels legs Ii are elevated or depressed, as may be required--for instan 3c, in adjusting the table vertically to correspond with the tile-machine, or in leveling the table on an uneven floor, or, if need be, to give an inclination to the table.

0 and D are drums on which operate the endless apron F, these drums being mounted, respectively, on shafts and D. Shaft D is journaled in suitable stationary boxes connected with the side frame, while shaft 0 is journaled in sliding boxes c,'the latter operating in slots a of the side frame. To each box 0 is attached a screw-rod c, the latter we tending through a hole in lug a of the adjacent side frame, the rod outside the lug being provided with hand-nut 0 by manipulating which latter the endless apron is tightened or relaxed, as may be required. Between the two drums the apron is supported by means 5 Patent No. 405,631, dated June 18, 1889.

Serial No. 286,501. (No model.)

of a series of rollers f, the trunnions of these rollers being journaled in suitable boxes connected with the side frames.

0 represents a bar of clay, one or more of which are forced out from the brick-machine onto the endless apron F, and the clay adheres suiiiciently to the apron to move the latter along with the bar of clay, and the apron in turn rotates the drums O and D.

Power is transmitted from drum D to mech anism that severs the bar or bars of clay into lengths for bricks or tiles, such mechanism being arranged as follows: Drum D is of such diameter that the drum is given just one revolution by means of the apron while the latter is moving the length of a given number of tile or briekin the present instance fourand consequently for every quarter-revolution of the drum D a brick or tile is severed. For severing the clay a wire 2' is provided, the wire being stretched across the open side of yoke I. The one end of yoke is provided with a hook I ,or some suitable device, for attaching the one end of the wire. The other end of the wire is connected with screw-rod 2', provided with thumb-nut 2' the parts being arranged substantially as shown for tightening the wire. Yoke I reciprocates on vertical ways J by means of mechanism as follows: On shaft D is mounted disk E and gear E, the latter engaging pinion II of shaft H, the diameters of gears E and II being as four to one. On shaft H are mounted two equal cranks h, set in line and connected by means of pitmen h with trunnions I of the yoke. WVith such arrangement of parts while the bar of clay is traveling the length of one brick or tile the yoke makes a stroke down and back, thereby severing the bar of clay, and the yoke returning to the place of beginning. For moving the yoke along in unison with the bar of clay while the wire is nu king its cut, in order that the cut may be at right angles with the bar of clay, I provide as follows: The vertical ways J are rigidly attached to horizontal rods J, the latter extending horizontally lengthwise of the table and reciprocating through guideboxes a and to, these boxes being connected with the side frames aforesaid. To the rear end of sliding rod J are pivotally connected at j the hook-dogs K. Disk E and gear E have each four laterally-projecting pins 9, arranged in quadrant and concentric order, 0pposing pins being set in line with each other. These pins are set at such radial distance from the axis of the shaft that they move in unison with the endless apron, and consequently move at the same speed as the bar of clay. The parts are so timed that just as the wire 1' from above approaches the bar of clay hooks 7c of dog K engage the passing pins 6, by means of which engagement the wire and yoke are moved along in unison with the bar of clay. Meanwhile the yoke and wire move downward in making the cut, and are moved upward on their return-stroke while the wire is backing out of its own kerf, and just as the wire has passed above the bar of clay pins 6 draw off of, that is, becom'e disengaged from, hooks 7a, whereupon the recoil of springs j instantly returns the cutting apparatus rearward to the place of beginning, such rearward movement being limited by collar 7' adjusted 011 rod J, the collar engaging box a Connected with boxes a are laterally-projecting pins a that limit the downward swinging movement of dogs K, and consequently support the dog during and after the disengagement of the dog from pins 6. L are handles for moving the machine, these handles being pivoted to the side frames, as shown, so that when left free the handles by gravity turn down to a depending position.

Usually an endless belt (not shown) receives the severed bricks or tiles.

In Fig. 1 three bars of clay are shown; but by changing the dies of the tile-machine a single and larger bar of clay might be substituted for the three smaller bars, if so preferred. The number and size of the bars of clay will depend on the size of the brick-machine and the discharging-dies thereof.

WVhat I claim is 1. I11 a brick or tile cutting machine, the combination, with horizontally-moving carrier, of cutter reciprocating 011 vertical ways, such ways being mounted 011 horizontallysliding bars, mechanism, substantially as i11- dicated, for automatically actuating the cutter by the movement of the said carrier, substantially as set forth.

2. The combination, with horizontally-mow ing carrier, of cutter reciprocating on vertical ways, said ways being mounted on sliding bars, the latter operating in a plane parallel to the movement of the carrier, mechanism, substantially as indicated, for operating the cutter and intermittently moving the cutter in unison "with the carrier, substantially as set forth.

3. The combination, with endless apron and drums for supporting the same, of supportingframe on which the journal-boxes of the said drums are supported, the said frames being open on the one side, substantially as indicated, whereby the endless apron may be removed from the table intact, substantially as set forth.

In testimony whereof I sign this specification, in the presence of two witnesses, this 11th day of May, 1888.
